SENSORS IN SMARTPHONE

SENSORS IN SMARTPHONE

         There are so many sensors ,that are inbuilt in our smartphones for many purposes.Here, we are going to see some standard sensors that take place in our smartphones.

ACCELEROMETER  SENSOR:

                          The accelerometer  detects the axis based motion sensing. It sense the changes in the orientation of smartphones with respect to x,y and z axis.

                          Today most of the camera apps provides various specifications like portrait mode or panorama mode,it looks like different,so these all features are based on this accelerometer sensor .

AMBIENT LIGHT SENSOR:

                           In this, the sensor detects the light around our environment. Working of autobrightness in our phone is due to this sensor.This sensor detects the light intensity around us and send the information to the operating system and based on that data operating system adjusts the brightness.

AMBIENT TEMPERATURE SENSOR:

                           The temperature sensor is used to detect the temperature around your environment.This is not a standard sensor for all phones.Only some special flagship phones like Galaxy S4 or S5 have this kind of sensors.

AIR HUMIDITY SENSOR:

                           This sensor is used to detect the humidity around your environment.This sensor helps in some advance fitness apps.

BAROMETER SENSOR:

                           Barometer used to detect atmospheric pressure. It can also detect the distance from sea level. It can basically do two tasks.First,if your phone has barometer will help GPS to accurately detect your location and the second one is your phone can help you to detect many fitness activities like tracking the steps you walk through the day etc.,

FINGER PRINT SENSOR:

                            Today, people who using smartphones are likes to put fingerprint for their security in phone. In that place, the fingerprint sensor play a great role. When you enroll your fingerprint for the first time, it creates a map of your fingerprint.Then,when the next time, it just matches its with the registered once. If it matches the phone will unlock.

GYROSCOPE SENSOR:

                            It is the advanced version of accelerometer . It works with accelerometer and it detects each degree of changes in orientation. It provides highly precious motion sensing. when you play racing games this is the sensor which senses your actions.

HARMFUL RADIATION SENSOR:

                            It is a specially designed sensor for special persons who need it. It is used to detect the harmful radiation in the nearby environment.

MAGNETOMETER SENSOR:

                           This sensor works like a compass in your phone.Whether we use Google maps or Apple maps, this magnetometer sensor tells where is north or some other directions.

NEAR FIELD COMMUNICATION SENSOR (NFC):

                          It is one of the farthest growing technology in smartphones,with wide the adoption of cashless payment. Two electronic devices which can communicate with each other by bringing them within 4 cm of each other. They can quickly send encrypted data to each other such as the payment details. If you have this in your phone you can do payments by just tapping it with on the NFC enabled device.

PROXIMITY SENSOR:

                         It detects the presence of object . This sensor detects the distance between sensor and object (generally your ear or hand). During phone calls , your screen automatically turned off, is due to  the action done by this sensor.
